''Antennaria dimorpha'' is a North American species of flowering plants in the daisy family known by the common name low pussytoes or gray cushion pussytoes.〔(Calflora taxon report, University of California, ''Antennaria dimorpha'' (Nutt.) Torrey & A. Gray Gray Cushion Pussytoes, low pussytoes )〕 It is native to western Canada (British Columbia, Alberta, Saskatchewan) and the western United States as far south as Riverside County in California and Rio Arriba County in New Mexico. It is generally found in dry areas. There are historical records of the species formerly occurring in northwestern Nebraska, but these populations appear now to be gone.〔(Biota of North America Program 2014 county distribution map )〕 ''Antennaria dimorpha'' is a small mat-forming perennial herb growing in a flat patch from a thick, branching caudex. The spoon-shaped leaves are up to about a centimeter long and green but coated with long, gray hairs. The erect inflorescences are only a few centimeters tall. Each holds a single flower head lined with dark brown and green patched phyllaries. It is dioecious, with male plants bearing heads of staminate flowers and female plants bearing heads of larger pistillate flowers. The fruit is an achene with a long, soft, barbed pappus. ==References==
